Article Synopsis
  • The study aimed to evaluate the effects of different resuscitation fluids on blood coagulation and related metrics in a controlled hemorrhage model using six cats.
  • Cats underwent three treatments over two months: no hemorrhage with sham resuscitation, resuscitation with lactated Ringer's solution (LRS), and resuscitation with Voluven (a starch solution). Blood tests were conducted at multiple time points.
  • Results showed that both LRS and Voluven led to significant prolongation of prothrombin time (PT) and activated partial thromboplastin time (aPTT), as well as reduced hematocrit (HCT) and platelet counts, indicating hypocoagulopathy

Objective: To compare the effect of invasive continuous positive airway pressure (CPAP), pressure-controlled ventilation (PCV) with positive end-expiratory pressure (PEEP) and spontaneous breathing (SB) on PaO, PaCO and arterial to central venous oxygen content difference (CaO-CcvO) in healthy anaesthetized dogs.

Study Design: Prospective randomized crossover study.

Animals: A group of 15 adult male dogs undergoing elective orchidectomy.

In order to develop a long-term anesthesia for flighty antelope species in field situations, two different protocols for induction and maintenance with an intravenous infusion were evaluated in wild-caught impala ( Aepyceros melampus ). Ten adult female impala were induced with two induction protocols: one consisted of 0.2 mg/kg medetomidine, 4 mg/kg ketamine, and 0.

There is a growing necessity to perform long-term anesthesia in wildlife, especially antelope. The costs and logistics of transporting wildlife to veterinary practices make surgical intervention a high-stakes operation. Thus there is a need for a field-ready total intravenous anesthesia (TIVA) infusion to maintain anesthesia in antelope.
